Let's divide 19087703 by 781
The aim is to understand the frequency of 781 in 19087703.

Going ahead to step 1:
781 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 781

Going ahead to step 2:
781 goes into 19 0 times with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 781

Advancing to step 3:
The number 781 fits into 190 0 times, leaving a remainder of 190.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 190, we end up with 190.
Take the next digit (8) from the dividend and append it to 190, then repeat: 1908 / 781

Step 4:
When dividing 1908 by 781, we get 2 with a remainder of 346.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 1562 away from 1908, we end up with 346.
Grab the next digit (7) from the dividend, add it to 346, then carry on: 3467 / 781

Going ahead to step 5:
781 goes into 3467 4 times with a remainder of 343.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Deduct 3124 from 3467 and we're left with 343.
Include the next digit (7) from the dividend after 343, then repeat: 3437 / 781

Advancing to step 6:
If we divide 3437 by 781, we get 4 and a remainder of 313.
Write down 4 as next digit of the result. 
Result so far: 244.0
Subtracting 3124 from 3437 leaves us with 313.
Include the next digit (0) from the dividend after 313, then repeat: 3130 / 781

Going ahead to step 7:
3130 divided by 781 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 2444.0
If we subtract 3124 from 3130, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 781

On to step 8:
The number 781 fits into 63 0 times, leaving a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 24440.0
If we take 0 away from 63, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 9:
781 can be fit into 630 0 times, resulting in a remainder of 630.
The number 0 becomes the next digit in our result. 
Result so far: 24440.0
If we subtract 0 from 630, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Going ahead to step 10:
If we divide 6300 by 781, we get 8 and a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 24440.08
Deduct 6248 from 6300 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
When dividing 520 by 781, we get 0 with a remainder of 520.
Record the quotient 0 as the next digit in the result. 
Result so far: 24440.08
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 12:
If we divide 5200 by 781, we get 6 and a remainder of 514.
Use 6 as the next digit of our solution. 
Result so far: 24440.0806
The remainder is 514 after subtracting 4686 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Let's proceed to step 13:
5140 divided by 781 is 6 with a remainder of 454.
Use 6 as the next digit of our solution. 
Result so far: 24440.08066
If we subtract 4686 from 5140, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

The final result is 24440.08066 with a remainder of 0.000454.
